LDK120C35R Description

Short technical summary and product information.

The STMicroelectronics LDK120C35R is a fixed output linear voltage regulator designed for various electronic applications. It provides a stable 3.5V output voltage with a maximum output current of 200mA. The regulator features a low dropout voltage of 0.3V at 200mA and a quiescent current of 60µA, making it suitable for power-sensitive designs.

 

Key electrical characteristics include a PSRR of 55dB at 120Hz to 10kHz and protection features such as over current and over temperature shutdown. The device operates over a temperature range of -40°C to 125°C.

 

This component is offered in a surface mountable SOT-323-5 package, as well as SC-70-5 and SOT-353 variants. Its small footprint and reliable performance make it a good choice for space-constrained applications requiring a regulated 3.5V supply.
